（1）吸附階段：有機廢氣經(jīng)過沸石轉(zhuǎn)輪吸附后直接達標(biāo)排放，沸石分子篩由于孔徑的大小能根據(jù)廢氣分子的大小和極性的不同進行選擇性的吸附。即使廢氣成分的濃度很低仍具有較高的吸附能力，且在高溫下扔具有很強的吸附能力，這是其他吸附劑不具備的。

(1) Adsorption stage: Organic waste gas is directly discharged after being adsorbed by zeolite wheels, and zeolite molecular sieves can selectively adsorb according to the size and polarity of waste gas molecules due to their pore size. Even if the concentration of exhaust gas components is very low, it still has high adsorption capacity, and it has strong adsorption capacity at high temperatures, which other adsorbents do not have.

（2） 脫附階段：沸石轉(zhuǎn)輪始終保持非常緩慢的旋轉(zhuǎn)，在廢氣處理區(qū)吸附飽和，在再生區(qū)把吸附在沸石里的有機廢氣通過熱空氣吹掃下脫附出來。熱空氣的溫度根據(jù)廢氣的成分而設(shè)定，沸石吸附大的特點就是沸石不可燃，脫附時可保持較高的脫附溫度因而可適用于很多沸點較高的廢氣成分，這一點是活性炭吸附+催化燃燒所達不到的。

(2) Desorption stage: The zeolite wheel always rotates very slowly, saturating the adsorption in the waste gas treatment area, and desorbing the organic waste gas adsorbed in the zeolite through hot air blowing in the regeneration area. The temperature of the hot air is set according to the composition of the exhaust gas. The characteristic of zeolite adsorption is that it is not flammable and can maintain a high desorption temperature during desorption, making it suitable for many components of exhaust gas with high boiling points. This is something that activated carbon adsorption+catalytic combustion cannot achieve.

（3）RTO燃燒階段：沸石轉(zhuǎn)輪實際上是個濃縮裝置，把低濃度大風(fēng)量廢氣里的廢氣分子捕捉、富集到沸石上面。當(dāng)脫附時就能用很小的熱風(fēng)從沸石中把廢氣分子吹掃出來。這時脫附出來的高濃度小風(fēng)量的廢氣就可直接進入RTO蓄熱式焚燒爐進行高溫焚燒。由于出來的廢氣濃度較高風(fēng)量較小，因此使用很小風(fēng)量的RTO設(shè)備，使用很低的輔助燃料就可以讓廢氣得到較好的凈化效果。

(3) RTO combustion stage: The zeolite wheel is actually a concentration device that captures and enriches exhaust gas molecules from low concentration and high airflow exhaust gas onto the zeolite. When desorbed, a small amount of hot air can be used to blow out the exhaust gas molecules from the zeolite. At this point, the high concentration and small airflow of the desorbed waste gas can directly enter the RTO thermal storage incinerator for high-temperature incineration. Due to the high concentration of exhaust gas and low air volume, using RTO equipment with very low air volume and using very low auxiliary fuel can achieve good purification effects on the exhaust gas.

（4）沸石轉(zhuǎn)輪恢復(fù)階段：沸石轉(zhuǎn)輪脫附區(qū)經(jīng)高溫再生后會使得沸石溫度很高，使吸附效果變差。因而要對經(jīng)過高溫吹掃過的沸石區(qū)域用補冷風(fēng)機進行降溫，降溫后的沸石又具有吸附廢氣的能力，周而復(fù)始循環(huán)往復(fù)吸附廢氣。

(4) Zeolite wheel recovery stage: After high-temperature regeneration in the zeolite wheel desorption zone, the temperature of the zeolite will be very high, resulting in a decrease in adsorption efficiency. Therefore, it is necessary to use a supplementary cooling fan to cool the zeolite area that has been blown by high temperature. The cooled zeolite also has the ability to adsorb waste gas, and it will cycle back and forth to adsorb waste gas.

沸石轉(zhuǎn)輪濃縮+RTO適用范圍

Zeolite rotary concentration+RTO applicable range

（1）沸石轉(zhuǎn)輪濃縮+RTO廢氣處理工藝主要運用于低濃度連續(xù)排放的廢氣治理；

(1) The zeolite rotary concentration+RTO waste gas treatment process is mainly used for the treatment of low concentration continuous emissions of waste gas;

（2）適用于不含有S、N、Cl、F等鹵素的廢氣，即燃燒后不產(chǎn)生新的副產(chǎn)物的廢氣成分，若有這些成分可在預(yù)處理階段除去；

(2) Applicable to exhaust gases that do not contain halogens such as S, N, Cl, F, etc., i.e. exhaust gas components that do not produce new by-products after combustion. If these components are present, they can be removed during the pre-treatment stage;

（3）廢氣的沸點不能太高比如大于300℃，這樣會導(dǎo)致吸附到沸石分子篩的廢氣在熱空氣的吹掃下長時間脫附不出來；

(3) The boiling point of exhaust gas should not be too high, such as above 300 ℃, as this will cause the exhaust gas adsorbed on the zeolite molecular sieve to be unable to desorb for a long time under the blowing of hot air;

（4）可適用于化工、涂料、醫(yī)藥農(nóng)藥制造、電子產(chǎn)品制造、家具制造行業(yè)、包裝印刷行業(yè)、涂裝、涂布行業(yè)、飼料化肥等涉及有機溶劑使用和有機廢氣排放的所有行業(yè)。只要滿足能被沸石吸附，且能脫附出來，高溫燃燒后不產(chǎn)生副產(chǎn)物的廢氣成分皆可使用沸石轉(zhuǎn)輪濃縮+RTO廢氣處理工藝。

(4) It can be applied to all industries related to the use of organic solvents and organic waste gas emissions, such as chemical engineering, coatings, pharmaceutical and pesticide manufacturing, electronic product manufacturing, furniture manufacturing, packaging and printing industry, painting and coating industry, feed and fertilizer industry, etc. As long as the components of the waste gas that can be adsorbed by zeolite and desorbed without producing by-products after high-temperature combustion are met, the zeolite rotary concentration+RTO waste gas treatment process can be used.
